Application of Superfish for the modelling of dielectric resonator structures

Superfish is a finite difference package written to solve the TM and TE resonant frequencies and field distributions in an RF cavity with two dimensional Cartesian or three dimensional cylindrical symmetry. Only the azimuthally symmetric modes are found for cylindrically symmetric cavities and the modes are found one at a time. In this paper Superfish is applied to the modelling of a dielectric resonator structure.
